lever toward wheel Move wheel up or

down to suit your requirements. Be sure all

wheels are in the same setting.

NOTE: Adjuster is properly positioned

when plate tab inserts into hole in lever.

BEFORE STARTING ENGINE

OIL

Your lawn mower is shipped without oil in

the engine.,

o Be sure mower is level and area around oil

fill is clean,,

• Remove engine oil cap and fill to the full line

on the dipstick.

• Use 27 ozs. of oil. For type and grade of oil

to use, see "ENGINE" in Maintenance

section of this manual.

o Pour oil slowly° Do not over fill.

o Check oil level before each use. Add oil if

needed. Fill to full line on dipstick

= To read properlevel, tighten engine oil cap

each time.

° Reinstall engine oil cap and tighten,,

• Change the oil after every 25 hours of

operation or each season. You may need

to change the oil more often under dusty,

dirty conditions.

GAS

° Fill fuel tank Use fresh, clean, regular

unleaded gasoline with a minimum of 87

octane. Do not mix oil with gasoline

Purchase fuel in quantities that can be used

within 30 days to assure fuel freshness

WARNING: Experience indicates that alcohol

blended fuels (called gasohol or using ethanol

or methanol) can attract moisture which leads

to separation and formation of acids during

storage. Acidic gas can damage the fuel

system of an engine while in storage. To avoid

engine problems, the fuel system should be

emptied before storage of 30 days or longer

Drain the gas tank, start the engine and let it

run until the fuel lines and carburetor are

empty. Use fresh fuel next season. See

Storage Instructions for additional information

Never use engine or carburetor cleaner

products in the fuel tank or permanent

damage may occur:

Gasoline filler cap Engine oil cap

TO START ENGINE

° To start a celd engine, push primer three (3)

times before trying to start. Use a firm push.

This step is not usually necessary when

starting an engine which has already run for

a few minutes.

• Hold operator presence control bar down to

the handle and pull starter handle quickly.

Do not allow starter rope to snap back°

= To stop engine, release operator presence

control bar.

NOTE: In cooler weather it may be neces-

sary to repeat priming steps. In warmer

weather over priming may cause flooding and

engine will not start. If you do flood engine,

wait a few minutes before attempting to start

and do not repeat priming steps.

o Forextremelyheavycutting,reducethe

widthofcutbyoverlappingpreviously

cutpathandmowslowly

. For better grass bagging and most

cutting conditions, the engine speed

should be set in the fast position.

° When using a rear discharge lawn

mower in moist, heavy grass, clumps of

cut grass may not enter the grass

catcher Reduce ground speed (push-

ing speed) and/or run the lawn mower

over the area a second time

,, If a trail of clippings is left on the right

side of a rear discharge mower, mow in

a clockwise direction with a small

overlap to collect the clippings on the

next pass.

• Pores in cloth grass catchers can

become filled with dirt and dust with use

and catchers will collect less grass. To

prevent this, regularly hose catcher off

with water and let dry before using

,, Keep top of engine around starter clear

and clean of grass clippings and chaff_

This will help engine air flow and extend

engine life

MULCHING MOWING TIPS

IMPORTANT: For best perfon'nance, keep

mower housing free of built-up grass and

trash See "Cleaning" in Maintenance section

of this manual

o The special mulching blade will recur the

grass clippings many times and reduce

them in size so that as they fall onto the

lawn they will disperse into the grass and

not be noticed Also, the mulched grass will

biodegrade quickly to provide nutrients for

the lawn Always mulch with your highest

engine (blade) speed as this will provide the

best recurring action of the blades

° Avoid cutting your lawn when it is wet. Wet

grass tends to form clumps and interferes

with the mulching action The best time to

mow your lawn is the early afternoon At

this time the grass has dried and the newly

cut area will not be exposed to the direct

sun_

• For best results, adjust the lawn mower

cutting height so that the lawn mower cuts

oft only the top one4hird ofthe grass blades

If the lawn is overgrown it will be necessary

to raise the height of cut to reduce pushing

effort and to keep from overloading the

engine and leaving clumps of mulched

grass. For extremely heaw mulching,

reduce your width of cut by overlapping

previously cut path and mow slowly.

o Certain types of grass and grass conditions

may require that an area be mulched a

second time to completely hide the

clippings When doing a second cut, mow

across or perpendicular to the first cut path.

. Change your cutting pattern from week to

week. Mow north to south one week then

change to east to west the next week. This

wilt help prevent matting and graining of the

lawn,

. The blade can be sharpened with a file

or on a grinding wheel. Do not attempt

to sharpen while on the mower

,, To check blade balance, drive a nail into

a beam or wall. Leave about one inch of

the straight nail exposed.. Place center

hole of blade over the head of the nail.

If blade is balanced, it should remain in

a horizontal position_ If either end of the

blade moves downward, sharpen the

wear. If catcher needs replacing, replace

only with a manufacturer approved

replacement catcher. Give the lawn mower

model number when ordering.

DRIVE WHEELS

Check front drive wheels each time before

you mow to be sure they move freely.

The wheels not turning freely means trash,

grass cuttings, etco are in the drive wheel

area and must be cleaned to free drive

wheels.

ENGINE

FUEL SYSTEM

IMPORTANT: It is important to prevent gum

deposits from forming in essential fuel system

parts such as carburetor; fuel filter; fuel hose or

tank during storage. Also, experience indicates

that alcohol blended fuels ( called gasohol or

using ethanol or methanoJ) can attract

moisture which leads to separation and

formation of acids during storage Acidic gas

can damage the fuel system of an engine

while in storage,

,, Drain the fuel tank.

" Start the engine and let it run until the fuel

lines and carburetor are empty,

,, Never use engine or carburetor cleaner

products in the fuel tank or permanent

damage may occur,,

- Use fresh fuel next season.

NOTE: Fuel stabilizer is an acceptable

alternative in minimizing the formation of fuel

gum deposits during sterage_ Add stabilizer to

gasoline in fuel tank or storage container,

Always follow the mix ratiofound on stabilizer

container; Run engine at least 10 minutes

after adding stabilizer to allow the stabilizer to

reach the carburetor. Do not drain the gas

tank and carburetor if using fuel stabilizer.
